Demographic histories
PSMC identified three major demographic histories: distinct insular and
continental histories within M. caurina and a single general
demographic history within M. americana with greater variance
relative to either M. caurina distribution (Fig. 3b). AllM. caurina distributions are lower (Ne) thanM. americana , with insular M. caurina exhibiting the
lowest Ne of all groups examined. Of the populations
examined, CHI has the highest historic peak in Ne, while
MAK had a larger effective population size recently.
